name
questions: laws of motion

1. what is a force?

a. the direction of an objects state of motion
b. something that changes an objects state of motion
c. the strength of an objects state of motion
d. none of the above

1. which of the following did newton not contribute to our scientific understanding of the world?

a. theory of gravity
b. calculus
c. laws of motion
d. theory of the solar system with the sun in the center

1. \an object that is in motion will stay in motion\ is part of:

a. newtons first law of motion
b. newtons second law of motion
c. newtons third law of motion
d. newtons fourth law of motion

1. that objects of greater mass require greater force to accelerate is:

a. newtons first law of motion
b. newtons second law of motion
c. newtons third law of motion
d. newtons fourth law of motion

1. that for every action there is an equal and opposite reaction is:

a. newtons first law of motion
b. newtons second law of motion
c. newtons third law of motion
d. newtons fourth law of motion

Explanation:

1. According to the definition of force, it is something that changes an object's state of motion.
2. Newton contributed to the theory of gravity, calculus, and laws of motion. The theory of the solar system with the sun in the center was mainly proposed by Copernicus.
3. "An object that is in motion will stay in motion" is part of Newton's First Law of motion (Law of Inertia).
4. The relationship that objects of greater mass require greater force to accelerate is described by Newton's Second Law of motion (\(F = ma\)).
5. "For every action there is an equal and opposite reaction" is Newton's Third Law of motion.

Answer:

1. B. something that changes an object's state of motion
2. D. theory of the solar system with the sun in the center
3. A. Newton's First Law of motion
4. B. Newton's Second Law of motion
5. C. Newton's Third Law of motion
